Finally, if you have defined `VULKAN_HPP_NO_EXCPETIONS` and compile for at least C++23, the constructors as described above are not available (they would potentially throw an exception which is not allowed then) but you have to use the construction functions. Those functions then do not return the created object, but a `std::expected<vk::raii::Object, vk::Result>`: Finally, if you have defined `VULKAN_HPP_NO_EXCEPTIONS` and compile for at least C++23, the constructors as described above are not available (they would potentially throw an exception which is not allowed then) but you have to use the construction functions.
